LANDAU-CARRIAGE-TOP LOCK.

SPECIFICATION forming part of Letters Patent No. 290,?349, datedDecember 18, 1883.

Application filed J une 11, 1883.

To aZZ whom it may concern:

Be it known that I, OLIVER S. OsBoRN, of New Haven in the county of NewHaven and State of Connecticut, have invented anew Improvement inLandau-Garriage-Top Locks; and I do hereby declare the following, whentaken in connection with the accompanying drawings and the letters ofreference marked thereon, to be a full, ciear, and exact description ofthe same, and which said drawi-ngs constitute part of thisspecificatiou, and represent, inr Figure 1, a top View; Fig. 2, an edgeView. Fig. 3 illustrates the operation, and Fig. 4 a longitudinalcentral section.

This invention relates to an nprovenentin the hooks or fastenings bymeans of which the parts of the top of a La'ndau and other carriages aresecured together when closed. The device usually employed for thispurpose is either a simple hook, necessitating that the parts be drawnclose together before the hook could be Secured, or aconbination of twohooks in such a manner that one Will reach when the parts are not indirect opposition and the other will draw the parts together.

The object of this invention is the construction of a device which,secured to one part, will engage the connection on the other part beforethe parts have been completely brought together, and at the same timedraw them tov gether without having recourse to a second hook.

The invention consists in a hook attached by'means of a pivot to onepart and a corresponding connection for said hook on the other part.When the hook has been engaged by revolving on its pivot through tworight angles, the two parts may be drawn close together.

(No model.)

\ B is the plate which forms the connection of the hook to one part; A,the plate upon the other part carrying the device to which the hook isSecured-that device here represented as a stud, O.

D is the strengthening-bar of the hook and is elevated so as to clearthe stud C in the manipulation of the hook.

H is a senicircular bar, forming the essential part of the book andpassing around the stud`C with its center at I. The hook H E I D issccured at the pivot I to the plate B by a spring-washer, K, and a nut,L; hence' there is no rattling, and the hook can be revolved through anentire circle. When the hook H E I D is revolved to the position seen inFig. 3, the bar D will pass just above the stud O, and the part H willbecome engaged in the stud C at its angle ofjunction with the bar D. Asthe revolution is continued the plate A, and with it the part of theLandau top to which it is attached, is drawn closer and closer to theplate B till the plates are in oppositiou, as seen in Fig. 1.

The amount of draw is shown ing distance from I to H.

I claim as my invention- The semicircular bar H, pivoted out of thecenter and provided 'with strengthening-bar by the vary- D, attached toone part of the carriage-top,

and a securing device, G, upon the other, the revolution of said bar Haround its pivot causing the two points of attachment *to approach eachother, substantially as set forth.
